Using the discovered OS Command Injection vulnerability in Linksys WRT54GL within a pentest

After releasing the OS command execution vulnerability in the WRT54GL router from Linksys last week there were some requests about how could we use this vulnerability for getting a remote shell.

First off all we have to analyze the firmware a bit. For this it is best to download the original firmware from the vendor and use the firmware-modification-kit or binwalk created by Craig Heffner and Jeremy Collake. Awesome toolkit from awesome guys.

So let’s extract and analyse the firmware a bit:

root@bt:~/images/firmware_mod_kit/firmware-mod-kit-read-only# ./ /root/images/FW_WRT54GL_4.30.15.002_US_20101208_code.bin linksyswrt54gl

Vendor: Linksys/Cisco

============ Vulnerable Firmware Releases: ============

Firmware Version: 4.30.15 build 2, 01/20/2011

============ Device Description: ============

The Router lets you access the Internet via a wireless connection, broadcast at up to 54 Mbps, or through one of its four switched ports. You can also use the Router to share resources such as computers, printers and files. A variety of security features help to protect your data and your privacy while online. Security features include WPA2 security, a Stateful Packet Inspection (SPI) firewall and NAT technology. Configuring the Router is easy using the provided browser-based utility.


Artikel in iX 01/2013 - Gezielt gebohrt Exploit-Tutorial, Teil III: Eigene Metasploit-Module entwickeln

Werkzeuge wie der Immunity Debugger, Metasploit, Mona oder Spike vereinfachen den Prozess der Exploit-Entwicklung an unterschiedlichen Stellen. Zwar können sie die manuelle Analyse nicht vollständig ablösen, aber wer diese Tools effektiv einsetzt, kann Schwachstellen deutlich schneller bewerten und daraus stabilere Exploits bauen.

Der Artikel findet sich in der aktuellen iX - 01/2013.

Viel Spaß beim Lesen,
